The directive legally requires this information. This value has been calculated from the acoustic power levels for ”Lifting” and ”Driving” and is only be used as a comparable value for different trucks. For the determination of the real environmental noise stress this value is less appropriate, as it is not representative of normal truck operation, which includes ”Idling”. NOTE Higher or lower noise emissions can exist during operation of the truck, for example due to type of operation, environmental influences and additional noise emission sources.

NOTE The frequency characteristic for the human body can not be used to determine the actual frequency load during operation. This load depends on the working conditions (condition of roadway, type of operation, etc) and must therefore be determined at the site, if necessary. The specification of hand and arm vibrations is required by law, even if the values, as in this case, do not indicate any danger.

Acoustic power level H 12 T - H 20 T Uncertainty
Technical description The 350 series fork trucks are designed for loading and stacking loads of up to 1.2 t with the H 12 T, 1.6 t with the H 16 T, 1.8 t with the H 18 T and 2.0 t with the H 20 T. They are of compact design and have a small turning radius. The trucks are therefore especially suitable for narrow passages and close working areas.

Engine
Description Operation
Brakes
The variable-displacement hydraulic pump and engine speed are simultaneously controlled by one pedal each for forward and reverse travel. With the hydrostatic drive, truck speed can be regulated from a standstill up to maximum speed with infinitely variable control in both directions. The double pedal control permits easy as well as safe and quick handling of the lift truck.
The hydrostatic transmission is used as service brake. The two multiple disc brakes integrated in the drive axle are utilised as a parking brake.
The engine fitted is a 4-cylinder, 4-stroke type with overhead camshaft and self-adjusting hydraulic tappets. It provides power to the hydraulic pumps of the lift truck at load-dependent speed.
Both hands are always free for steering and control of the work movements. The result is quick reversing and efficient stacking.
The engine is cooled with a closed-loop cooling system with a recovery tank.
Another version allows control of the truck speed with one accelerator pedal (single-pedal control) and the direction of travel with a directional switch.
The engine speed varies depending on the lift and truck speed. The electronic control keeps it constantly at the maximum limit, independent of the loads experienced. Thus the engine power available always corresponds to the speed set by the position of the accelerator pedal.
There is only one control lever (main control lever) for controlling the work motions lifting, lowering and tilting. Further control levers are supplied for the operation of additional attachments.
The engine is fired via the transistorised ignition system, ignition coil, distributor and spark plugs. The fuel used is liquefied gas stored in the gas cylinder or LPG tank. CAUTION Components conducting exhaust gases or outgoing air may become hot depending on conditions and duration of use.
Hydraulic system The travel drive consists of a variable-displacement pump and two fixed-displacement motors installed as a unit in the drive axle, and a tandem pump (fixed displacement) for the working hydraulics and power steering system. Travel direction and speed are controlled with two accelerator pedals via the variable-displacement pump.
The work motions can be controlled with two control levers (single lever version).
When the engine is stopped, the multiple disc brakes are applied = automatic braking. The brake pedal is also designed as parking brake so that it must be locked mechanically when the truck is shut down.
Steering The steering system consists of a hydrostatic steering, which operates the rear wheels by the steering wheel via the steering cylinder. The steering can also be operated when the engine is stopped, but a greater effort is required to turn the steering wheel.
Electrical system The electrical system is supplied with 12 VDC by a threephase current alternator. A 12 V battery is installed for starting the engine.
LHC control LHC = Linde Hydraulic Control The electronic control unit governs the engine speed and the swash plate angle of the hydraulic pump automatically to maintain a preset travel speed (wheel rpm). System faults are detected by the electronic control unit and indicated with a warning light. Depending upon the fault, a travel speed reduction and even shutoff of the engine may occur as a damage prevention measure. Any faults occurring can be determined with the diagnostic unit.
The fixed-displacement motors in the drive axle are supplied with oil by the variable-displacement pump, and they each power a drive wheel via a reduction gear.

Safety instructions for the LPG system
The accident prevention rules in some countries prescribe that the fork lift truck must be checked at least once a year for proper working condition by trained personnel. Please contact your authorised dealer in this regard.
The lift truck can be operated at full speed directly. Avoid sustained high loads on the working hydraulic system and the travel drive in the first 50 hours of operation.
Linde wishes you a long use of your LPG truck with maximum safety.
Tighten wheel fasteners daily before each shift and after each wheel change until they are seated firmly, i.e. until no further tightening is possible.
WARNING When LP gas leaks out, there is an immediate danger of explosion resulting in the risk of burns. This is particularly the case when: - leaks occur on the LPG system, - the engine does not start or starts poorly.
Operation of industrial trucks in the plant area ATTENTION Many plant areas are so-called limited public traffic areas. We advise you to check if your company liability insurance covers any damages occurring with your fork truck against third parties on "limited" public traffic areas.
Tighten opposite wheel fasteners to a torque of 210 Nm. NOTE Observe the tightening instructions on the tag attached to the steering column.

Forward travel
Changing the travel direction
CAUTION Travel on gradients over 15 % is not allowed, due to the prescribed minimum brake applications and truck stability characteristics. Before driving on steep slopes, you should consult your dealer. The climbing ability rates given in the data sheet were derived from the drawbar pull of the truck and they apply only for crossing obstacles and for low differences in ground level. Always drive consistent with road conditions (uneven surfaces, etc.), especially hazardous work areas, and the load.

-
Release the actuated accelerator pedal. The hydrostatic drive will act as service brake.
-
Depress the accelerator pedal for the opposite direction of travel. The truck will now be accelerated in the selected direction.
-
During travel, keep both feet on the accelerator pedals in order to be able to control all movements of the truck easily.
-
The accelerator pedals can be operated from forward to reverse travel directly. The hydrostatic drive will brake the truck to a standstill and then accelerate it in the opposite direction.
CAUTION When using rear view mirrors it should be noted that the latter are only provided to monitor the rear traffic area and that reversing is only allowed with a direct view in the reverse direction of travel.
Depress the right accelerator pedal (2) gently. The truck will drive at a speed depending on how far the accelerator pedal is depressed.
NOTE Quick flooring of the accelerator pedal is not recommended as the maximum acceleration rate is regulated automatically.
Reverse travel -
Depress the left accelerator pedal (3) gently. The truck will reverse at a speed depending on how far the accelerator pedal is depressed.
Start the engine.
-
Elevate the forks slightly and tilt the mast back.
-
-
Push the parking brake lever (1) forward to disengage the brake pedal (4).
Slowly release the depressed accelerator pedal. The hydrostatic travel drive will act as service brake.
-
When stopping on gradients during upgrade travel, leave both feet on the pedals and equalise any drive slippage due to technical reasons by depressing the pedal slightly, or
-
depress the brake pedal for a long stop.
-
When dismounting from the truck with the engine running, for example, in order to briefly perform some action in close vicinity to the truck (opening a gate, unhitching a trailer, etc.), the brake pedal must be depressed and locked, open the seat belt. Shut down the engine if making a long stop. When leaving the truck unattended, remove the ignition key.

Stopping
-
Single-pedal model Starting the engine NOTE If at all possible, avoid frequent engine starts and short duty cycles so that the engine can reach its operating temperature. Frequent cold starts increase engine wear. NOTE In case of low ambient temperatures (below 10° C), let the engine run at least 1-2 minutes between starting and stopping in order to avoid malfunctions in the LPG system.
350 804 3351.0705
NOTE The directional lever (3) and all other control levers must be in the neutral position. NOTE On certain Linde fork trucks (eg with container overhead guard, swivel seat) the torso clearance is reduced. Therefore only persons with a headroom of 30 mm between the head and overhead guard should operate this truck.
Operation -
-
Sit down on the driver’s seat. Apply the seat belt. Brake pedal (4) locked (engine will start only with brake pedal engaged). Insert the switch key (2) into the ignition switch. Turn the key switch clockwise from the zero position to first position. The electrical system is now switched on. The LHC warning light (8) will illuminate. After a few seconds, the gas level of the LP gas bottle can be read on the meter (1). The battery charge indicator (7) and the engine oil pressure (6) lights will illuminate red. Turn the key switch fully clockwise. As soon as the engine has started, release the switch key. If engine does not start after 20 seconds, discontinue the starting procedure and repeat as described.
Pause at least one minute between starting attempts to save your battery. It the engine fails to start after three attempts, refer to the troubleshooting guide for the LPG engine.
WARNING If malfunctions and starting problems occur on your truck, the LPG system must be checked by an expert with special knowledge of this system. -
The battery charge indicator, engine oil pressure and the LHC warning lights should go out as soon as the engine is running. The engine rpm is governed by demand automatically. WARNING Do not operate the engine in unventilated enclosures. Danger of poisoning!
NOTE Do not warm up the engine in idle. Drive the truck briskly with a load. The engine will quickly reach operating temperature.

Closing the gas cylinder or LPG tank* shutoff valve
-
Place the directional lever (3) to the neutral position.
-
-
Turn the switch key (2) to the zero position.
Close the gas cylinder or gas tank* shutoff valve (6) tightly immediately after stopping the engine.
-
Remove the switch key when leaving the truck unattended.
-
NOTE The brake engages when the engine is stopped. Set the parking brake lever (1) vertical.
-
Depress the brake pedal (5). The brake pedal engages in this position.
When it is freezing park the truck as far as possible in closed rooms, e.g. garages, because liquefied petrol gas evaporates only sufficiently at temperatures over -5 °C (propane), respectively +5 °C (propane/butane) to start the engine.
WARNING Garages, storage areas and service workshops must be well ventilated. Note that LP gases are heavier than air. They collect on the ground, in pits and other low areas and form explosive air-gas mixtures (see local accident prevention regulations).
ATTENTION Do not park the truck in halls or garages in the immediate vicinity of equipment radiating heat or radiators.

Steering system, braking system
Operation Parking brake
Steering Due to the hydrostatic power steering, very little effort is required to turn the steering wheel. This is especially advantageous when stacking in narrow aisles. - Start the engine and drive the truck. - Turn the steering wheel as far as possible through the full cycle. WARNING Contact your dealer if steering becomes hard or if excessive play exists. Do not drive the lift truck with a faulty steering. Turning radius - H 12 T ............................................................... 1948 mm - H 16 T ............................................................... 1990 mm - H 18 T ............................................................... 2026 mm - H 20 T ............................................................... 2105 mm
350 804 3351.0705
Service brake -
Allow the accelerator pedals to return to the neutral position. The hydrostatic drive will act as a service brake. The braking can be controlled from gentle to abrupt braking by allowing the accelerator pedals to return to the neutral position slowly or quickly.
ATTENTION For emergency braking depress the STOP pedal located between the accelerator pedals. This will bring the truck to a full stop.
The multiple disc brakes are used as a parking brake.
Applying the parking brake: -
Stop pedal ATTENTION The stop pedal (1) does not operate a sensitive service brake but a firmly-acting parking brake. Avoid using it while driving as the traction wheels can block und the load possibly slide off the forks. In unfavourable circumstances the engine may also stall. In this case wait 30 seconds before restarting it until the traction drive pump has returned to neutral. NOTE It is recommended that the operator acquaint himself with the function and effect of this brake without a load on the truck. Drive on a roadway without traffic at a slow speed.
Set the parking brake lever (2) to the vertical position. Depress the stop pedal (1). The stop pedal will lock in this position.
Releasing the parking brake: NOTE The multiple disc brakes will only be released when the engine is running. -
Push the parking brake lever (2) forward to disengage the stop pedal.
WARNING Contact your authorised dealer if faults or signs of wear become evident in the braking system. Do not drive the truck with a faulty braking system.

Before lifting a load
Operation
350 804 3351.0705
Before lifting a load, check the load capacity diagram (1) on the engine cover. WARNING When attachments are fitted, check the capacity plate (2) for that equipment. Figures stated in the capacity diagram or plate apply to compact and regular loads and must not be exceeded, as this will reduce the stability of the fork truck and the strength of the forks and mast. The maximum capacity is determined by the height of lift and the load centre distance. NOTE Check the load capacity limits and contact your authorised dealer before transporting - off-centre or swinging loads, - loads with the mast tilted forward or the load not near the ground, - loads beyond the centre of gravity, - before operating attachments, - loads at wind force 6 and higher.
Example Load centre distance ............................................... 600 mm

Inspection and maintenance as required
Clean and spray the lift chains
Clean the lift truck NOTE The necessity of cleaning depends on the use of the truck. If used with aggressive media such as salt water, fertilizer, chemicals, cement, etc., clean the truck thoroughly after every use. Hot steam or intensive degreasing solution should be used with the utmost care! If not, the grease in the lubricated-for-life bearings will dissolve and leak out. As regreasing is not possible, damage to the bearings will result. Don’t wash the truck whilst the engine is running or hot.
Regularly remove inflammable debris especially on or in the area of parts with a high temperature (such as exhaust pipes).
D350/018
When cleaning with compressed air, remove sticking dirt with a cold cleaner. Clean the oil filler openings, surrounding areas and grease nipples before lubrication.
NOTE The lift chains must be cleaned if the dust on the chains prevents penetration of the lubricant. -
Place a container under the mast.
-
Clean the chain with paraffin derivatives such as washing petrol (observe manufacturer’s notes on safety).
-
When using a steam jet, clean without additives.
-
After cleaning, blow dry the chain at once to remove any water in the chain links and on the surface. Move the chain several times during this procedure.
-
Immediately spray Linde chain spray onto the chain while moving it.
ATTENTION Lift chains are safety components. The use of cold cleaners, chemical cleaning agents and caustic or acidic and chlorinated fluids can be a direct cause of damage to the chains.
D350-3/041
350 804 3351.0705
ATTENTION When cleaning with a water jet (high pressure or steam jet cleaning device, etc.) do not directly expose the electrical or electronic components as well as the connectors to the jet. If this cannot be avoided, cover them first.

Maintenance
Inspection and maintenance as required Clean the air filter
Maintenance
Clean with compressed air
NOTE Cleaning the air filter element is necessary only when the air filter restriction indicator in the composite instrument illuminates. A restricted air filter results in loss of power and increased engine wear. Careful and regular servicing of the air filter is therefore essential for the engine. Carry out all services on the air intake system with the engine stationary. Do not start the engine when the filter element is removed. Open the bonnet.
-
Screw off the wing nut (2) and remove the air filter cover (1).
-
Screw out the nut (4) and pull out the air filter element (3).
-
-
To clean the filter element (3), blow dry compressed air at max. 5 bar pressure from the inside to the outside until the filter is free of dust. Before installing the cleaned air filter element, examine it for damage eg at paper of filter element, rubber seals, for dents or bulges on the metal frame.
-
Using an inspection lamp, examine the paper part of the filter element for cracks and holes.
-
Renew a damaged filter element.
NOTE Mark every servicing on the filter element. Discard the filter element if it has been cleaned 5 times, if damaged, after 1000 service hours, or at least every 12 months. -
Reinstall the filter element into the filter casing. Make sure that the filter element is not damaged and that the seal on the filter casing fits properly.
-
Note the arrow symbol on the dust bowl indicating the top.

Let the engine run warm to evaporate any residual water and to prevent corrosion.
-
Check connectors, coolant hoses and pipes at the radiator and hydraulic oil cooler for leaks.
-
Renew cracked hoses, retighten loose clamps, if necessary.
If used in clean and dry areas, truck servicing every 500 service hours is sufficient as a rule. For mixed use inside and outside, it is recommended that the lubrication interval be halved. In an environment with dust, dirt, water and possibly de-icing salt or chemicals, weekly lubrication will extend the service life of the bearings substantially. NOTE Preferably lubricate the bearings with less grease more often than a lot of grease less frequently.

Fuel and oil recommendations Engine oil Oil grade and viscosity CCMC specification: G4/G5 API classification: SF/SG/SH Volkswagen specification: 500 00/501 01 A special high-grade multigrade oil has been filled at the factory that can be used all year round, except in extreme climates. As the trouble-free operation and long service life of the engine depends upon a good engine oil, use only high-grade engine oil when topping up. The specifications given on this page must be stated on the container, either alone or together with other specifications. When adding oil, the oils can also be mixed.
NOTE Single grade oils can usually not be used the year round because of their limited viscosity range. These oils should only be used in extreme climates. Regardless of the oil change intervals, change the engine oil at least once a year. Do not add any additives of any kind to the lubricating oils.
86
ATTENTION Used oil must be stored safely outside the range of children before being disposed of. Never allow the oil to sicker into the sewer system or the ground. Due to the disposal problem and the required special tools and expertise, have the engine oil and filter changed by your authorised dealer.
350 804 3351.0705
Select the viscosity range of the oil according to the table. If the ambient temperature exceeds the specified range only briefly, the oil does not need to be changed.
A - Multigrade light oils B - Multigrade oils
Fuel and oil recommendations Hydraulic oil
Lubricating grease
Recommendation for normal duty:
Linde heavy duty grease with a lithium base and EP additives and MOS2.
Hydraulic oil ISO - L - HM 68 to ISO 6743 - 4 or HLP ISO VG 68 to DIN 51524, T.2 (factory filling), average oil temperature 60 °C - 80 °C. Hydraulic oil recommendation for heavy duty: Hydraulic oil ISO - L - HM 100 to ISO 6743 - 4 or HLP ISO VG 100 to DIN 51524, T.2 for heavy and multi-shift operation, operation in extreme climate zones or at high ambient temperatures, average continuous oil temperature over 80 °C. For normal and heavy duty:
350 804 3351.0705
Hydraulic oil ISO - L - HV 68 to ISO 6743 - 4 orHVLP ISO VG 68 to DIN 51524, T.3 (multigrade oil). NOTE The choice of the proper oil depends on the operating temperature of the oil in the hydrostatic drive. The above recommendations can only be guidelines.
Designation to DIN 51825-KPF 2N-20 (see Parts Catalogue for the Order No. Never mix grease types that are not lithium-based.
Coolant Only use coolant additive with a monoethenglycol base with corrosion inhibitor. Do not mix with coolant additive containing enthanolamine. Temperature -25 oC -30 oC -35 oC
Coolant additive 40 % 45 % 50 %
Drinking Water 60 % 55 % 50 %

Safety rules for LP gas (excerpt) Observe the accident prevention rules of your national Industrial Trade Association. Liquefied petrol gases are BUTANE, PROPANE and butanepropane mixtures. They are supplied in LPG cylinders or gas tanks for the operation of IC engines. The operating pressure of these gases depends on the ambient temperature and it may reach 25 bar or more. WARNING Released LP gas becomes gaseous instantly so that the formation of a hazardous and explosive atmosphere is immediately given.
350 804 3351.0705
WARNING No naked flame (stoves, storm lanterns, spark generating activities, etc.), no smoking in garages or when carrying out work on the LP gas system!
Responsibility of employer and employees The employer must ensure that the industrial trucks must be operated and serviced by persons instructed in the operation and servicing of these trucks and who can be relied on to perform their tasks reliably. LPG systems on trucks may only be taken into operation if they are in the proper working condition. The employer must prepare operating instructions for the industrial truck in an understandable form and language, which contains all the information required for safe operation. The operating and service staff must be acquainted with the operating instructions. The operating instructions must be available for and observed by the operating and service staff at all times.
A. During operation 1. Close the cylinder shutoff valve and main shutoff valve before disconnecting the pipe or hose connection. Loosen the union nuts on the cylinders slowly and only slightly at first, otherwise the gas still in the line will spurt out. CAUTION LP gas can cause frostbite on bare skin!
Do not expose LPG tanks and pipes and hoses and their fittings for gas in the liquefied phase to inadmissible extraneous heat. 2. Removable LPG tanks (LPG cylinders) must be mounted on the truck so that they are in the horizontal position and with the cutout in the collar pointing down. During installation and removal, the gas outlet fitting on the cylinder valve must be sealed with a locknut tightened securely with a special key. Before connecting the gas cylinders, check the connecting fittings for proper condition. After removal, screw the cylinder cap immediately onto the cylinder with the locknut. 3. Open the valves slowly! Do not open or close valves by striking them with tools. Danger of sparks causing an explosion. ATTENTION Only use CO2 powder type fire extinguishers or CO2 gas extinguishers for LP gas fires. 4. Leaking gas cylinders must be taken out of use. They should be emptied immediately in the open air by releasing the gas in accordance with all the relevant safety measures and then tagged as leaking. When returning damaged gas cylinders, notify the distributor or his representative (e.g. service station attendant) immediately of the damage, in writing if possible.
5. The entire LPG system must be monitored continually for safe condition, particularly for leaks. It is forbidden to use the vehicle with the gas system leaking. Use soapy water, a Nekal solution or another foam-forming agent when checking for leaks. Do not inspect the LPG system for leaks with a naked flame. 6. Be sure to adjust the LPG systems so that the exhaust emissions are kept as low as possible. 7. Frozen parts of the LPG system may only be thawed with hot water, hot sandbags or the like. Naked flames, red-hot objects, etc. can cause explosions. 8. The manufacturer’s installation instructions must be followed when changing single parts of the system. Cylinder valves and main shut off valves must also be closed for the procedure. 9. The condition of the electrical system of industrial trucks powered by LP gas should be monitored continuously. Sparks can cause explosions if there are leaks in the gas system. If a LPG powered industrial truck has not been used for a long time, ventilate the garage thoroughly before starting the vehicle or operating its electrical equipment. 10. Your industrial trade association and the responsible trade supervisory authority should be notified immediately of any explosions involving gas cylinders or LPG systems, even if no injury resulted from the accident. Damaged parts should be kept in safekeeping until the conclusion of the investigation. 11. LPG powered vehicles may only be operated in entirely or partially enclosed spaces if no dangerous concentrations of exhaust components hazardous to health can accumulate in the breathing air.

Safety rules for LP gas (excerpt) B. In garages, storehouses and repair shops 1. Close the cylinder and main shut off valves immediately after parking the vehicle.
5. Electric lights installed in these rooms must have a tightly fitting sealed protective cover with a strong basket protector.
2. LPG powered industrial trucks may only be parked in wellventilated rooms above ground level. They may not be parked near openings to rooms below ground level. Keep a safe area around parked trucks in which there are no cellar openings and doors, pits and similar hollows, uncovered sewer openings, air and light shafts, and inflammable materials.
6. Close the cylinder and main shutoff valves during work in repair shops and protect the LPG cylinders from the influence of heat. A responsible person must check if all valves, especially cylinder valves, are closed before work breaks or at the end of the day's work. Do not perform any work involving fire, in particular welding and cutting jobs, near the LPG cylinders. Do not store LPG cylinders in workshops, even if they are empty.
3. Removable gas cylinders may only be changed in garages in which the formation of an explosive atmosphere has been prevented. 4. Follow the special regulations related to the storage of gas cylinders or national regulations. For example, gas cylinders may not be stored
-
in rooms under ground level, in staircases, in hallways of houses and multiple-story buildings, small yards and passages and gates or in their immediate vicinity, at stairs of open-air facilities, at specially marked rescue routes, in garages, in workrooms.
Please observe the section "General Requirements for Gas Cylinders" in the Technical Rules for Gas Cylinders (TRG 380 and 404) or your local regulations.

WARNING Exhaust gases are poisonous. Ensure adequate ventilation of garages!
To prevent injuries to persons and/or destruction of the contactless transistorised ignition system, observe the following points when working on components of the transistorised ignition system: -
Disconnect and connect ignition system cables - also high-voltage cables and test leads - only with the ignition turned off.
-
If the engine is to be operated at starting speed without firing (e.g. when testing compression), pull the highvoltage cable (terminal 4) from the distributor and earth it.
-
Use a rapid charging system as a starting aid only for 1 minute and with max. 16.5 Volt.
-
Wash the engine only with the ignition turned off.
-
Disconnect the battery completely before carrying out electric welding or spot-welding.
-
Do not connect a capacitor to terminal 1 (-).

7. Garages, storehouses and repair shops must be well ventilated. Do not forget that LP gases are heavier than air. They accumulate over the floor, in inspection pits and other low spots and there they can form a dangerous and explosive air-gas mixture.
